The customer service is exemplary (shout out to Joe W.) and the employees are all so nice. By far the best selection I've ever seen! Great YT channel as well. They buy for cash or store credit and also do trades. I've done several trades and they all went very smoothly! Thanks ABC!

What a great company! Not only do they make cool things (Mothman kit!), their customer service is top-notch. I mis-typed a delivery address resulting in my order being returned. As soon as I contacted Atlanta Brick Co, they told me how to get it re-sent and were extremely nice about it. Good people!
